In what sense is the measure you refer to more "correct" than another?

Let me ask you a related question:
Which is the correct method to estimate the variance (i.e. sigma squared) of
a normal population from a sample of N measurements (values) from this
population?
a. The maximum likelihood method (i.e. the (sum(xi-xbar))/N
b. The unbiased estimate (i.e. the (sum(xi-xbar))/(N-1)
And you are assessing a software package for correctness in reporting a
variance result?
